I have switched to running the e85 in a 540 BBC. The motor has a 14-71 blower shop blower @ 5% under driven and more than pleased with the results. The Dominators were converted using the Quick Fuel conversion kit. The question I have is, how large are the squirters are you finding that is needed to come out of the hole without a stumble.
The Quick Fuel kit came with 47's for squirters and there was a slight hesitation, so I changed to 50's, but slowed the motor down to idle at about 1000 rpm from 1150-1200 RPM. I had a huge hesitation when I did that. I drilled some old squirters to 61. It was the smallest I had, except for some 45s. I expected that to be quite a bit to much, but I did want to see if that was the correct direction I need to go. It does not hesitate at all now. I have a playback tachometer that I can print from and it shows it still is not snapping the rpm from 1-3000 like I think it should. The 61s definitely helped and actually feels good.
Has anyone tried different squirters with e85 and a blower and found they need larger than 61s for the squirters?
I am talking about idling the motor around 1000 rpm, in gear with the boat flat in the water and then hit the accelerator peddle to bring it out.
I think bigger squirters are needed, but the end of the season is over for me to try something else.
So, I am looking for opinions and possibly experience for suggestions and thoughts.
I am running this in a Cole TR4 flatbottom, 11X16 prop and 29 gears.
